Description

A Bulb crops harvester

The present invention relates to an agricultural crop harvesting machine such as a turfgrass, a turban, a ginger, and the like. More specifically, the present invention relates to an agricultural machine harvesting machine, So that the harvesting operation of the alfalfa crop can be facilitated by separating the small algae that have clumped in the clay that has been crushed by the crooking blade.

Turmeric is a perennial herb that is native to India and cultivated in the tropics and southern China. Ulgum can be said to be a plant of origin, and Ulgum is divided into Ulgum and Turmeric depending on the area to be medicated. Ulgum uses the roots of plants, and turmeric uses stem roots of plants. The taste of turmeric is wider than that of Ulgum, and its color is darker than Ulgum. Root shape is round like 2 ~ 4 branches like a cone shape. It is similar to ginger but it has a dark yellow color. The golden pigment is the main component of curcumin and the unique smell of gilt is the main component of essential oil. As a spice crop, a variety of varieties are grown in India and are used worldwide for dyeing, pungent flavor, aroma and other purposes.

It is said that Ulgum was produced as a kind of souvenir in the early Joseon Dynasty and used as a spice. Jindo County, Jeonnam Province, is the main province, which accounts for 70% of the cultivation area. Jeju Island is mainly grown in Seogwipo and Namhaean area. There are about 50 species of Ulgum.

On the other hand, in the above crops such as gilt, ginger, and taran, when the harvesting time of the harvest is small, there is a problem in that the harvesting work is slow and inefficient .

Conventional underground crop harvesters such as Patent Documents 1 to 4 have used an elliptical sprocket to shake the conveying chain or attach an eccentric weight to a drive shaft to vibrate the whole harvester in order to solve this problem These problems still exist in harvesting small-sized rice paddies, ginger, taro, and other crops.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 5 show the structure and operating state of an alfalfa crop harvester according to an embodiment of the present invention. In the alfalfa crop harvester 1 according to the present embodiment, a tow portion 12 is provided at a front upper portion A lower conveyor 30 formed to be inclined upward from a rear portion of the crockery blade 20 to a rear end of the frame 10. The lower conveyor 30 includes a frame 10, The crusher is installed on the upper part of the frame 10 and separated from the lower conveyor 30 so as to crush the clay when the crushed grains and the clay are transported backward along the lower conveyor 30, And a conveyor (40).

In the present embodiment, a disk-type soil cutting blade 50 is provided on the front left and right sides of the frame 10 so that it can be pulled by the tractor while being guided by the crockery blade 20 installed inside the frame 10, It is possible to easily separate the soil on the left and right sides of the gutter and the gravel soil on the inside of the gutter to reduce the resistance to be applied when the harvester is towed.

In the figure, reference numeral 14 denotes a skid attached to the rear lower portion of the frame 10, 16 denotes a power transmission shaft connected to the PTO (POWER TAKE OFF) of the tractor, 18 denotes a frame 10 ) To the rear drive sprocket (31).

Further, in the present embodiment, the rear end of the frame 10 is provided with a swinging foot (hereinafter referred to as a swinging foot) for shaking off the ground and the soil which are dropped along the lower conveyor 30, 60. The operation structure of the rocking motion will be described later.

The lower conveyor 30 is a conveying conveyor that is basically used in the underground crop harvester, and a detailed description thereof will be omitted. However, the lower conveyor 30 is provided so as to be inclined upward at a predetermined angle from the front to the rear of the frame 10, The soil and the roots extracted by the blade 20 are transported to the rear of the frame 10 so that the roots and the roots are separated naturally and the roots and the roots that are not separated naturally in the course of the transportation are separated by the pressing action of the upper conveyor 40, The structure and function of the upper conveyor 40 are as described below.

The upper conveyor 40 is adjustable in spacing with the lower conveyor 30. The top end of the upper conveyor 40 is rotatably supported on the frame 10 by a rotary shaft 42, And the rear portion of the upper conveyor 40 moves up and down to the hydraulic cylinder 44 fixed to the rear upper side of the frame 10.

When the hydraulic cylinder 44 is contracted, the rear end of the upper conveyor 40 is heard The distance between the lower conveyor 30 and the lower conveyor 30 is increased. When the hydraulic cylinder 44 is extended, the rear end of the upper conveyor 40 is lowered, and the distance from the lower conveyor 30 is narrowed.

The upper conveyor 40 is rotated in an endless track manner by a hydraulic motor 43 axially coupled to the drive sprocket 41 at the rear end. The hydraulic motor 43 is a variable- And can be controlled according to the situation.

The distance between the rotation direction and the speed of the upper conveyor 40 and the distance between the lower conveyor 30 and the lower conveyor 30 is such that the soil is crushed without damaging the crushed soil due to the size and viscosity of the clay due to the type and size of the crop, The upper and lower conveyors 30 and 40 may be controlled in the same direction (clockwise direction in the drawing) as shown in FIG. 4, for example, (Not shown) passing between the upper and lower conveyors 30 and 40 are transported rearward along the lower conveyor 30, and the resistance is increased by the rotational force of the upper conveyor 40 in the opposite direction So that the clay located therebetween is rubbed in the opposite direction from the top and bottom in the opposite direction and finely crushed. At this time, the rotating speed of the upper conveyor 40 is The lower conveyor 30 is slower than the rotating speed of the lower conveyor 30 so that the crushing can be performed while the backward transfer of the clay and the crane is continuously performed.

5, the upper and lower conveyors 30 and 40 are rotated in opposite directions, that is, the lower conveyor 30 is rotated clockwise as shown by arrows, and the upper conveyor 40 is rotated counterclockwise The soil and the alumina placed between the upper and lower conveyors 30 and 40 are crushed by the simple pressing action between the upper and lower conveyors 30 and 40 so that the backward conveyance is performed swiftly The state shown in FIG. 5 shows the case of harvesting in a field with a small crushed soil and low viscosity, as compared with the case shown in FIG.

Since the upper and lower conveyors 30 and 40 are attached to the left and right sides of the chain C at both ends of the chain so that the round bar or the pipe P is maintained at a predetermined interval, It is preferable that the broken soil is dropped below the lower conveyor 40 through the gap between the round bar and the pipe and the distance between the pipes P of the conveyors 30 and 40 is made so as not to fall down , And a support sprocket (32) is provided in the middle so as to prevent sagging of the lower conveyor (30) in the process of conveying the soil and the roots.

In the present embodiment, the PTO power of the tractor is transmitted to the lower conveyor 30 by the rear drive sprocket 31, so that the lower conveyor 30 is rotated in the clockwise direction in the figure, The rod 64 is connected to the camshaft 62 which receives the power from the driving sprocket 31 of the lower conveyor 30 and is rocked.

In the drawing, reference numeral 33 denotes a driven sprocket of the lower conveyor 30, reference numeral 45 denotes a driven sprocket of the upper conveyor, and reference numeral 46 denotes a lower conveyor 40 in contact with the clay when the upper conveyor 40 is rotated. As shown in Fig.

As described above, according to the present invention, the conveyor is spaced up and down on the inner side of the frame, and the soil and the roots crushed by the cutting blade pass between the upper and lower conveyors, It is possible to solve the phenomenon in which the smooth transport is not performed and the troubles such as the crushing of the clay by hand after the crushing can be solved, because the crushed clay is finely crushed without damaging the crane It has a beneficial effect of maximizing the harvesting efficiency of the alfalfa crops.
